N,N-双十二烷基乙二胺的合成及摩擦学性能
Synthesis of N,N-didodecylethylenediamine and its tribological properties
摘要
Abstract
N,N-didodecylethylenediamine was prepared via nucleophilic substitution by using ethylenediamine and 1-bromododecane. The effect of reaction conditions on the synthesis of N,N-didodecylethylenediamine was investigated experimentally. The results show that the yield of N,N-didodecylethylenediamine is 45.5% under the following reaction conditions:the molar ratio of 1-bromododecane to ethylenediamine was 2.4∶1,and the reaction was effected for 8 h at reflux temperature. The chemical structures of the prepared compounds were characterized by FTIR, 1H-NMR spectra and elemental anal. New application of N,N-didodecylethylenediamine as additives in lubricants was explored. The tribological properties of the N,N-didodecylethylenediamine as additives in PEG 400 were evaluated using a four-ball tester. The results show that the PB value of PEG 400 could be increased from 696 N to 862 N when the adding weight percent of N,N-didodecylethylenediamine is 2%.关键词
